Shilpashastra (iconography)
: archive.org: Catalogue of Pancaratra Agama Texts (shilpa)1) 鲹ٲԲԲ (रत्नन्या�) refers to preliminary rites (performed before an icon can be placed into position) which involves “digging a pit�, as discussed in chapter 7 of the Brahmarātra section of the Բٰܳṃh: an encyclopedic Sanskrit text written in over 3500 verses dealing with a variety of topics such as yoga, temple-building, consecration ceremonies, initiation and dhanurveda (martial arts).—Description of the chapter [پṣaṇoś]: Icons may be made of stone, metal, gems, wood or clay. As for stones, these are classified into four groups-named according to the four castes—and it is told which kinds should be used for making proper icons. [...] Before an icon can be placed into position, ٲԲԲ-rites must be taken care of, details of which include digging a pit, lining it with “neuter� bricks, constructing the pedestal-base, etc. (1046-111). [...]
2) 鲹ٲԲԲ (रत्नन्या�) refers to the “rites of gem burial�, as discussed in chapter 38 of the Ādikāṇḍa of the Ჹⲹśīṣaṃh: a large Pāñcarātra Āgama consisting of roughly 6500 verses dealing primarily with architecture, temple-building and consecration rituals and iconography.—Description of the chapter [ٲԲԲ]: This chapter turns to the procedure involved in placing the icon on the pedestal in the garbhageha-sanctuary. Where exactly the icon is to come in the sanctuary room is given. The rules vary according to the posture of the icon and its identity (1-15). The pedestal (which is “neuter,� and made of stone only, 62a) is installed first and in it (in a cavity made for the purpose) gems, etc. are placed—while offerings of grains and gems are simultaneously made in the various courtyards to “protect� the central gem-burial (17-28a). The steps for performing ٲԲԲ-rites are given, along with mantras. Certain alternatives to follow for some of the details enjoined are also given (28b-59). Thinking of the pedestal as Śrī, after ū, the icon of the Lord is fixed on it. For all 岹, the پ-icon is called ī (61b).
: Shodhganga: Vaisnava Agamas And Visnu Images鲹ٲԲԲ (रत्नन्या�) refers to the ceremony of “deposit of precious stones� at the completion of beeswax modeling (ūṣṭ), as defined in treatises such as the Pāñcarātra, Pādmasaṃhitā and Vaikhānasa-āgamas, extensively dealing with the technical features of temple art, iconography and architecture in Vaishnavism.—The Vaiṣṇava Āgamas insist that the metal icons should be made through a casting process called Madhūcchiṣṭa-kriyā. [...] The finishing work include two important activities—a) deposit of precious stones (ٲԲԲ) and, b) fixing of pedestal (ᲹṭiԻԲ). 鲹ٲԲԲ is considered to be very essential for the permanent presence of the divinity in the icon.

Shilpashastra (शिल्पशास्त्र, śilpaśāstra) represents the ancient Indian science (shastra) of creative arts (shilpa) such as sculpture, iconography and painting. Closely related to Vastushastra (architecture), they often share the same literature.
Vastushastra (architecture)
: Google Books: Consecration Rituals In South Asia鲹ٲԲԲ (रत्नन्या�) (lit. “placement of gems�) refers to a ceremonial ritual within the Śaiva tradition involving the placement of a consecration deposit below the pedestal of an iconic image or a ṅg (a representation of the divine). The 鲹ٲԲԲ ritual involves placing precious and semiprecious stones, among other items, below the pedestal, symbolizing the sanctification and empowerment of the deity or object of worship. 鲹ٲԲԲ is one of the earliest consecration rituals described in Sanskrit texts, with mentions dating back to texts like the Bṛhatsaṃhitā from the 6th century and the Guhyasūtra of the Niśvāsatattvasaṃhitā from the late 7th century.

Vastushastra (वास्तुशास्त्�, vāstuśāstra) refers to the ancient Indian science (shastra) of architecture (vastu), dealing with topics such architecture, sculpture, town-building, fort building and various other constructions. Vastu also deals with the philosophy of the architectural relation with the cosmic universe.
